About this trial
This randomized phase III trial will compare the outcomes of three treatment modalities for early-stage glottic laryngeal cancer (T1-T2N0): transoral CO₂ laser microsurgery (TLM), volumetric modulated arc therapy (VMAT), and MRI-guided stereotactic ablative radiotherapy (MRI-SABR). The primary endpoint is local control (LC). Secondary endpoints include laryngectomy-free survival (LFS), progression-free survival (PFS). overall survival (OS), functional voice, swallowing and breathing outcomes, treatment-related complications, and the evaluation of radiomic and dosiomic biomarkers. Patients will be randomized in a 1:1:1 ratio. Total planned enrollment is 105.
